Percy was teasing Gordon that his train was late, but it turns out to be coal trucks and he teased James to stay in the shed as the Fat Controller has a special for him. However it turns out that the Fat Controller is away and this made James cross. When the Fat Controller returned, he was cross with both Percy and James. The two big engines wanted to get back at Percy for teasing them and they told Percy about 'Backing signals'. As Percy came across a new signal that goes meaning the line is clear, he went backwards. As the driver told him about the signal, Percy wanted to get away quick, but it was too late as Gordon passed him. In the end, Percy was wise about signals.

PRO:

- A great way to teach kids about signals.

CON:

James' face slightly coming off.

Percy is not your usual stupid engine in this episode. When you see an episode of Thomas nowadays, you see Percy wanting to make friends with animals, wanting to play with other engines or pushing a Calliope up a hill to make steam. Here you see Percy making a mistake because he Naive, he has no idea about these new signals and you can tell he was wise about them. This episode is also a good example to teach kids about signals, there are many different types of signals that you see on heritage railways and this episode shows it.

Though I do have one con and that was James' face, it was funny looking but mistakes are made and they learn.
